Patent number: 10240979Abstract: A pulse generator generates high voltage discharge pulses in a manner that may be controlled and monitored. Pulse generator operation may be monitored to measure characteristics associated with pulse generator operation and to produce pulse generator data representative of those characteristics. Pulse generator operation may be monitored by monitoring the discharge pulses produced by the pulse generator and/or the charging of energy storage elements within the pulse generator in preparation for a subsequent discharge pulse. The pulse generator data may be used, for example, to identify pulse generator wear or degradation, to identify problems with pulse generator operation, and/or to control pulse generator operation for improved performance. The pulse generator may also be configured and controlled to generate a high-voltage initiation pulse to initiate a subsequent discharge pulse while being contained within a relatively small form factor.Type: GrantFiled: June 29, 2015Date of Patent: March 26, 2019Assignee: Cascodium Inc.Inventors: Patrick J.

Patent number: 7495220Abstract: An uncooled infrared sensor can be used for a plurality of applications such as fire fighting, surveilling a border or any desired area, and limb sounding. The uncooled infrared sensor includes manually or automatically adjustable optics that receive an electromagnetic signal, focus the electromagnetic signal and provide a focused electromagnetic signal to a focal plane array. The focal plane array includes a plurality of detector devices disposed in rows and columns to form the focal plane array. Each detector device is constructed so as to have a reduced pitch and provide a maximum number of detectors within a minimum square area of the focal plane array. Each detector device detects the focused electromagnetic signal incident upon it, converts the focused electromagnetic signal into a sensed signal and outputs the sensed signal so that the focal plane array provides a plurality of sensed signals.Type: GrantFiled: April 28, 2006Date of Patent: February 24, 2009Assignee: BAE Systems Information and Electronics Systems Integration Inc.Inventors: Richard Blackwell, Neal R.

Patent number: 7254366Abstract: A system and method communicate signals between a portable unit and a communications system. The portable device communicates with a base unit using inductive coupling. The base unit is further connected to a wider communication system such as a telephone network. Multiple, orthogonally arranged transducers are used in the base unit to provide a more complete magnetic field and to prevent mutual inductance nulls which are otherwise present in a magnetic field. The use of short-range inductive coupling minimizes the power requirements and limits interference with other sources. The inductive coupling may also be used to recharge a battery in the portable device.Type: GrantFiled: March 18, 2005Date of Patent: August 7, 2007Assignee: Aura Communications, Inc.Inventors: Vincent Palermo, Patrick J. Cobler, Neal R. Butler

Patent number: RE39982Abstract: A magnetic communication system includes a transmitter have a single coil transducer, and a receiver having a three orthogonally oriented coil transducers. The signal processing circuitry in the receiver adjusts the phases of the signals received by the three transducers to produce signals which are in-phase. The signals are then summed to provide an output signal from the receiver. The processing circuitry adjusts the phases of the incoming signals either serially or in parallel. Transmissions from the receiver to the transmitter are also phase adjusted in accordance with the same adjustments used in reception.Type: GrantFiled: June 14, 2001Date of Patent: January 1, 2008Assignee: Aura Communications Technology, Inc.Inventors: Vincent Palermo, Patrick J. Cobler, Neal R. Butler
